<!-- [TOC] -->

A [divider](https://m3.material.io/components/divider)<!-- {.external} --> is a thin line
that groups content in lists and containers.

Dividers can reinforce tapability, such as when used to separate list items or
define tappable regions in an accordion.

## Usage

Use full width dividers to separate larger sections of unrelated content.

![A full width divider separating two paragraphs of "Lorem ipsum"](images/divider/usage.webp "Full width divider example")

```html
<section>
  <p>Lorem ipsum...</p>
  <md-divider></md-divider>
  <p>Lorem ipsum...</p>
</section>
```

### Inset dividers

Use inset dividers to separate related content within a section.

![A list of design system names separated by an inset divider](images/divider/usage-inset.webp "Inset divider example")

```html
<section>
  <p>Material 2</p>
  <md-divider inset></md-divider>
  <p>Material 3</p>
</section>
```

Inset dividers are equally indented from both sides of the screen by default.
Use `inset-start` or `inset-end` to change this.

```html
<section>
  <p>Material 2</p>
  <md-divider inset-start></md-divider>
  <p>Material 3</p>
</section>
```

## Accessibility

Dividers are decorative by default and not announced by assistive technology.

Add a
[`role="separator"`](https://developer.mozilla.org/en-US/docs/Web/Accessibility/ARIA/Roles/separator_role)<!-- {.external} -->
attribute to non-decorative dividers that should be announced.

```html
<ul>
  <li>Item one</li>
  <md-divider inset></md-divider>
  <li>Item two</li>
  <md-divider role="separator"></md-divider>
  <li>Item three</li>
  <md-divider inset></md-divider>
  <li>Item four</li>
</ul>
```

## Theming

Divider supports [theming](../theming/README.md) and can be customized with CSS
custom property tokens.

### Tokens

Token                    | Default value
------------------------ | --------------------------------
`--md-divider-color`     | `--md-sys-color-outline-variant`
`--md-divider-thickness` | `1px`

*   [All tokens](https://github.com/material-components/material-web/blob/main/tokens/_md-comp-divider.scss)
    <!-- {.external} -->

### Example

![A customized divider with a different color and thickness](images/divider/theming.webp "Divider theming example.")

<style>
:root {
